The ground-breaking Gemasolar Concentrated Solar Power (CSP) plant with storage near Seville, Spain, has marked its second anniversary with another breakthrough – producing round the clock power for a record breaking 36 consecutive days.

The power plant, owned by Torresol Energy, has been producing energy for two years since its official opening on October 4, 2011. It was the first large scale solar tower power plant to use molten salt, which captures heat during the day so that the plant can still produce energy at night.

Torresol said in a statement marking the anniversary that the plant has exceeded the expected results and has demonstrated the sturdiness of the design. Producing energy 24/7 for 36 consecutive days from solar energy “is something that no other plant has performed so far.”
